Because a calibrated monitor has no bearing on the printed output. They are two separate paths. Each needs to be properly color managed, independently, to give a good match between them.

What a calibrated monitor does give you is a reference: this is what the print should look like. But you still have to watch your calibration targets, especially luminance (not too bright, or the prints will come out too dark).

The short answer is that - in the PS print dialog - you set PS to manage color and pick the correct profile for the printer and paper.

Then open the printer driver and disable printer color management (because you don't want double profiling). You still need to have the correct paper type selected (this has to do with the amount of ink the printer will use).

All this varies a bit from printer to printer, so if you repost include details about your printer.

I did all those things and still did not get the printed photo EXACTLY as on screen. I use : eye-one display 2 ( for screen calibration ) , HP Photosmart C7283 All-in-One printer and Photoshop CS3 . With the calibration I get a new monitor profile. I used Color Handling Photoshop Manages Colors , Printer Profile Adobe RGB ( 1998 ) disabled color management in the printer dialog.

Adobe RGB (1998) is not a printer profile, it is an image profile. A printer profile is specific to your printer, paper type, and ink used. They are generated by printing a standard chart, measuring each color, and processing the data to generate a printer profile. You can purchase software and hardware to use in generating printer profiles, or you can use a service to generat them for you. In some cases you can download printer profiles for your printer/paper combination. You are missing one step in the printring process (you don't have a printer profile).

b2martin is correct. You need to watch your profiles and where they go. Think of it this way: you have a source profile, which is the document profile, Adobe RGB. Then you need a destination profile which is specific for the printer/paper/ink.

Unfortunately, HP is one of those companies that don't trust people to think for themselves, they believe they have to do it for you. So it's a very real possibility that they don't even supply profiles. Look through the dropdown list for things like "hp premium glossy" or similar (whatever paper you're using). If there's nothing there, you'll have to resort to "Printer manages color", and pray that the printer understands what Adobe RGB is. This is one of those things I hate HP for, a pity since they make very good hardware.
